Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Variable star studies play an important roles in understanding the physical properties of the galaxies and clusters they are present in. The stars in globular clusters are believed to have formed roughly at the same time (although there is also mounting evidence that some clusters have formed via several episodes of star formation), from the same primordial material, and with the same composition. This should lead to a homogeneity in certain fundamental properties of the stars within each cluster, but with differences between the clusters. Knowledge about these properties, such as metallicity, age, and kinematics, are therefore important. One way to obtain better constraints on some of these physical parameters is to study the population of variable stars, especially RR Lyrae stars. Observing variable stars in different galaxy environments makes it possible to relate the types of variable stars to the stellar populations in their host galaxies.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 72 pp. Englisch.…

Se cree que las estrellas de los cúmulos globulares se formaron aproximadamente al mismo tiempo (aunque cada vez hay más pruebas de que algunos cúmulos se han formado a través de varios episodios de formación estelar), a partir del mismo material primordial y con la misma composición. Esto debería conducir a una homogeneidad en ciertas propiedades fundamentales de las estrellas dentro de cada cúmulo, pero con diferencias entre los cúmulos.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -L'étude des étoiles variables joue un rôle important dans la compréhension des propriétés physiques des galaxies et des amas dans lesquels elles sont présentes. On pense que les étoiles des amas globulaires se sont formées à peu près en même temps (bien qu'il y ait de plus en plus de preuves que certains amas se sont formés après plusieurs épisodes de formation d'étoiles), à partir du même matériau primordial et avec la même composition. Il devrait en résulter une homogénéité de certaines propriétés fondamentales des étoiles au sein de chaque amas, mais aussi des différences entre les amas. Il est donc important de connaître ces propriétés, telles que la métallicité, l'âge et la cinématique. Une façon d'obtenir de meilleures contraintes sur certains de ces paramètres physiques est d'étudier la population d'étoiles variables, en particulier les étoiles RR Lyrae. L'observation d'étoiles variables dans différents environnements galactiques permet de relier les types d'étoiles variables aux populations stellaires de leurs galaxies hôtes.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 68 pp. Französisch.…
